Letter to the Editor: ‘On Quantile‐based Asymmetric Family of Distributions: Properties and Inference’

Abstract

We show that the family of asymmetric distributions studied in a recent publication in the International Statistical Review is equivalent to the family of two‐piece distributions. Moreover, we show that the location‐scale asymmetric family proposed in that publication is non‐identifiable (overparameterised), and it coincides with the family of two‐piece distributions after removing the redundant parameters.
